To all whom it may concern:

Be it known that 1, JOHN B. Bneovnrs, a citizen of the United States ofAmerica, and resident of Holyoke, in the county of Hampden and State ofMassachusetts, have in vented certain new and useful Improvements inTater-Heating Apparatuses, of which tl'ic i following is a full, clear,and exact description.

character indicated which will be available tremely inexpensive.

66 tain of the parts all substantially as hereinparatus an inclosedhollow axially vertical This invention relates to an apparatus forheating the water in an ordinary kitchen boiler tank comprised in theplumbing arrangements of a house, or for heating the water in anotherreceptacle as it may be practicable in some cases to do.

This heating apparatus is designed to operate independently of any waterfront heater in a stove, and to do the work of such water front heater,although it may be employed in some cases as an auxiliary thereto.

The principal object of the invention is to provide a .water heatingapparatus of the for heating considerable quantities of water by theemployment of a gas or other suitable burner in very much less time thanhas heretofore been necessary; and the apparatus has furthermore beendevised with a view to producing a gas heating apparatus which, byreason ofthe construction and organization or coiiperativearrangement ofthe arts thereof, is comparatively simple an ex- The invention comprisesin .a heating apannular metallic body, a supply pipe leading thereintofor water t osbe heated, a hot water delivery pipe therewith connectedand leading from the inclosed annular chamber therein, and a gas burnerbelow, and for heating the annular body.

The invention furthermore includes a construction of annular inclosedheater body havin a multiplicity of metallic studs connecte with andextended transversely from the circular walls thereof together with anarrangement of gas burner whereby the et flames thereof Wlll impinge, orbe directed against or relatively to both the annular bot toms ofthe'heater body and the studs projec'ting from the side walls thereof.

The invention furthermore consists in certain particular combinationsand arrangements of parts and the constructions or cerafter fullydescribed and set forth in the claims.

In the drawings :Figure 1 shows the improvedheater in central verticalsection connectcd'it'or operation in conjunction with an ordinarykitchen boiler tank. Fig. 2 is a plan icw of parts, on a larger scale,as seen below .the plane indicated by line 2-2, Fig. l, thesamcparticularly showing the compound gas heating burner. Fig. 3 is aseclional view on line 33, Fig. 1. Line l1, on Fig. 3; indicates theplane on'which=p0rtion of the view Fig. l, which is in section, istaken. Fig. t is a plan view, and Fig. 5 is a side elevation of thewater heating appa ratus, the inclosing casing or shell in Fig. 5 beingrepresented 1n section as taken on the line 5-5, Fig. 4;. 4

Similar characters of reference indicate corresponding parts in all ofthe views.

In the drawings,A represents the heaterbody constructed as an inclosed,liollow axially Vertical annular cast iron or other me tallic casingprovided with a multiplicity of metallic studs a a extended radially, orsubstantially transversely, with suitable spacin one from another fromthe outer c lindrical surface of the body; and said ody also has asimilar series of inwardly projecting metallic studs a connected withand radially projected from its inner wall.

B represents an ordinary house boiler tank V from which the pipe I)leads,-:t'rom the lower portion thereof into the annular chamber in Ahas formed thereon or attached thereto" neur the base thereof aplurality of compara- Lively short outwardly extending lugs d which arevertically perforated.

The letter D generally represents the compound gas burner provided as'apart of the present apparatus. This burner comprises into the mainannular burner, air in con unc-- tion with such gas being taken into the'burner by well known provisions indicated at f and requiring herein noparticular description,

llhe burner D is supported by being suspended from the low portion ofthe heater body A through means of L-shaped members g asparticularlyrepresented in Figs. 1,. 2

' and 5 which have connections with the outer sideof the main burnerbody f while their vertical limbs are extended upwardly through theperforations in the aforementionecl lugs (Z of the heater body and aretherewith connected by nuts 13, 13, or other equivalent fastenings.

The L- haped supporting members, being tubular, in communication withthe chamber in the main annular burner f and being upwardly openconstitute a plurality of jet burners directed outside of and parallelwith the eriphery of the heater body and for heating the outwardlyprojecting studs a in line therewith; and there are in addition toticularly representedby 9* a considerable number of further similarL-shaped tubular members 9' making with those 9* a circular the severaltubular L-shaped members parseries of upwardly directed gas burner jets,all taking their gas and air supply from the main burner f and forthoroughly heating all of the outwardly extending'radialstuds of theheater body. A short L-shapcd tubular member y' is connected with themain annular burner f at the inner side of the latter, and this member jhas connected at its upstanding portion a circular burner 7' providedwith upwardly open jet holes 15' directed into the circular verticalspace within the heater body A and efiective for the heating of theinner wall of such body principally through the medium of the inwardlydirected studs 21 with which the body is internally provided. The heatfrom the flames or gas jet of the compound burner constituted by themain annular burner f, the

concentrically arranged secondary burner j and the outwardly andupwardly branching tubular burner members 9, 9* is conserved by theprovision of the thin metal sheath or shell F which is of somewhatlarger diameter than the heater body A, having studs ments thereof, saidcasing being open atf both top and bottom,-its top, however, in thepresent instance being extended somewhat above the top of the heaterbody A and spaced from said eoaeer is providedwith an internal flange71: receivingsupports on posts or studs m, m and retained by screwsm-,-such posts extending upwardly from the top of the heater body andbeing cast integrally therewith or other wise provided thereto.

The entire heating apparatus has for the support thereof a constrictivemetallic strap or band G preferably made in separable halves heldtogether by clamping bolts 0, 0, and comprising as a whole a band likeportion 18 for engagement around the boiler tank B and a band, likeportion 19 for enga cment around the upper peripheral portioh of theheater body, which latter at its top has a slight flange 20 which restson the upper edge of the supporting band 19.

The chief advantage and value resulting from the: present invention areobtained from the capability of the apparatus to heat any considerablequantity of water for do-' inestic use in a surprisingly small time, it1 being appreciated that surfaces of the heater body are presented to beheated, and the same are heated directly at the base at the peripheryand at the inner wall by the action of gas flame not only in relation tothe periphery and inner wall, but also in rela;-

tion to the metallic stud provided at and transversely pro ecting fromsuch walls;

and while an amplitude of gas may be burned for the required heating {ofthe water, such gas burning need not be continued for any extended time,long run the heating apparatus is reasonably economical, as well asquick acting.

The transverse studs, in the apparatus as I have constructed it, are allintegrally cast so that in the with the annular heater body, but I may7, 1

construct the body, equipped with the studs in the arrangementshown,.and more or less numerous, as may be considered desirable byforming them separately and uniting or connecting them with the body inany of several manners known to be practicable. And other minor changesmay be made within the scope of my present invention. without departingtherefrom or, sacrificing the substantial advantages thereof. 2

The tube or rod t axially located inthe central space within the heaterbody prevents the jet flames from the central burner. from merging oneinto another, but on the other hand insures that the heat therefrom willbe distributed around about in relation to the many internal studs a Iclaim 1.
